2070 super will drop from 1965mhz to 300mhz during timespy and then crash

[Bloodshotport]

I don't know what the problem is with my GPU. All my games just recently started crashing on me, so I decided to run Time Spy and it couldn't run through the second graphics test. I looked into the charts and saw that the card would hit a hard dip down to 300mhz and then shoot straight back up to 1965mhz. I'm not savy on Overclocking and only really mess around with fan speeds through Afterburn. Any suggestions would be really helpful as I Don't want to mess with and break anything in my PC
